Definitions

  • the present invention relates to articles of furniture in general, and more particularly to a convertible sitting/reclining furniture article.
  • Still another object of the present invention is to construct the furniture article of the type here under consideration in such a manner that the extension element is arrested in its extended position by the pivotal mounting arrangements.
  • a sitting furniture article convertible into a reclining furniture article comprising a main frame; a seat element; means for supporting the seat element at a predetermined elevation above ground; a bed frame which can be pulled out of and pushed into the main frame in a drawer-like manner and includes a front side, a rear side and two lateral sides; an extension element; and means for mounting the extension element on the bed frame for displacement between a retracted position and an extended position in which the extension element is disposed at the predetermined elevation to form an extension of the seat element.
  • each of the kinematic linkages includes a steering lever pivotally mounted at a first region of the extension element and at a first portion of the bed frame and arranged closer to the front side of the bed frame, and two steering links arranged more remotely from the front side of the bed frame and adjacent to the steering lever and articulately connected to one another at a connection region, that one of the steering links is pivotally connected to a second region of the extension element at a predetermined distance from the first region while the other of the steering links is pivotally connected to a second portion of the bed frame which is spaced from the first portion by a distance exceeding the predetermined distance, and that the steering links assume a straight-line orientation with respect to one another in the extended position of the extension element to block the connection region against pivoting in at least one pivoting direction thereof.
  • a further advantage of the construction according to the present invention results from the fact that, for all intents and purposes, the pivotal movement range of the mattress element does not extend beyond the area which is predetermined by the outline of the bed frame so that such a furniture article can be used even under circumstances where the available space is limited.
  • the corresponding pivotal mounting arrangement assumes its arrested condition when the mattress element reaches its extended position, so that there is no need for providing any additional support, for instance a covering element, on which the mattress element would rest in its extended position.
  • the configuration of the bed frame, especially the shape and arrangement of a front covering plate thereof can be determined exclusively on the basis of optical and esthetic appeal considerations, without regard for any stability-determined dimensioning.
  • the sitting furniture article further comprises two abutment pins mounted on the extension element in a stationary manner and on the bed frame, respectively, at the regions of the respective steering links and in directions away from the steering links and towards the steering lever.
  • the steering links include respective abutment noses at their regions facing the respective abutment pins.
  • the sitting furniture articles further comprises, at each of the kinematic linkages, a tension spring which is connected with one end thereof at the first region of the extension element and with the other end thereof at the connecting region of the steering links.
  • FIGS. 1 to 3 are sectional views of a sitting furniture article of the present invention in various positions thereof;
  • FIGS. 4 and 5 are views similar to those of FIGS. 1 to 3 but after the sitting furniture article has been converted into different forms of a reclining furniture article;
  • FIGS. 6 to 9 are simplified side elevational views of one pivotal mounting arrangement employed in the sitting furniture article of FIGS. 1 to 5, together with parts of a mattress element and bed frame, in different relative positions.
  • FIGS. 1 to 5 thereof taken in conjunction with one another, it may be seen that the reference numeral 10 has been used therein to identify a main frame, while the reference numeral 11 designates a seat frame which can be pulled out of the main frame 10.
  • a mattress element 12 is pivotally mounted on the seat frame 11 by means of two laterally arranged kinematic linkages 20 in such a manner that the mattress or extension element element 12 can be pivoted up from a non-use or collapsed position which is depicted in FIG. 1 of the drawing into a use or extended position which is shown in FIGS. 4 and 5 of the drawing and in which the mattress element 12 is situated at the same elevation as a seat cushion or seat element 14 which is supported on the seat frame 11.
  • the kinematic linkages 20 are mounted, on the one hand, on the mattress element 12 and, on the other hand, on a bed frame 13.
  • a free front side of the bed frame 13 is provided with a front frame covering element 15.
  • the bed frame 13 is provided with rollers or casters by means of which it is movably supported on a floor. The bed frame 13 can be pulled out of the seat frame 11 until it abuts against a non-illustrated end abutment.
  • FIG. 2 illustrates a beginning of a pivoting of the mattress element 12 out of its collapsed position.
  • FIG. 2 as well as in FIG. 3, it can be very clearly seen that at first the free front side of the mattress element 12 is lifted while the oppositely located rear side remains situated underneath a projecting edge region of the seat cushion 14.
  • the kinematic linkages 20 provide the pivoting axis for such pivoting movement.
  • FIG. 4 illustrates the conversion of the original sitting furniture article into a reclining furniture article in which the seat cushion 14 and the mattress element 12 are situated at the same elevation, while a head rest 16 is so pivoted in a known manner that it bridges an intermediate space which has come into being between the seat cushion 14 and a back rest 17 as a result of the conversion of the sitting furniture article into the reclining furniture article.
  • FIG. 5 of the drawing Another position of the sitting furniture article is shown in FIG. 5 of the drawing. It may be seen here that the seat frame 11 with the associated seat cushion 14 is now situated at the region of the main frame 10, while the mattress element 12 is pivoted up in the above-described manner to the elevation of the seat cushion 14, so that there is obtained in this manner a possibility, which may be preferred by the user of the sitting furniture article, of sitting on the sitting furniture article with outstretched legs.
  • FIGS. 6 to 9 of the drawing show one of the kinematic linkages 20 in various positions thereof.
  • the kinematic linkage 20 is shown to include a steering lever 21.
  • the steering lever 21 is mounted, on the one hand, on the bed frame 13 and, on the other hand, on the mattress element 12, in each instance in a pivotable manner. In the illustrated construction, the steering lever 21 is arranged in the direction toward the free front side of the mattress element 12.
  • One of such steering links 22 and 23 is connected to the mattress element 12 while the other is connected to the bed frame 13, also in a pivotable manner.
  • FIG. 6 of the drawing shows the kinematic linkage 20 in a position corresponding to the non-use or collapsed position of the mattress element 12, this particular position being also illustrated in FIG. 1 of the drawing.
  • the kinematic linkage 20 corresponds to a five-bar linkage, that is, it is inherently unstable by itself.
  • This instability condition changes at the commencement of the pivotal movement of the mattress element 12 towards its extended position, inasmuch as the steering links 22 and 23 come into abutment at the region of their common pivot 24 with the bottom side of the mattress element 12, which means that the link region between the steering link 23 and the mattress element 12 is blocked and, as a result of this blocking, the kinematic linkage 20 becomes a four-bar linkage. In this manner, there is obtained, of necessity, a stable condition of the kinematic linkage 20.
  • the kinematic linkage 20 is illustrated in a position which it assumes when the mattress element 12 is in its extended or use position corresponding to that depicted in FIGS. 4 and 5 of the drawing.
  • the steering links 22 and 23 are disposed in a straight position with respect to one another, that is, they extend along a common straight line.
  • the abutment nose 28 which has been mentioned before in connection with the description of FIG. 8 remains in engagement with the abutment pin 25.
  • Another abutment nose 29 is provided on the other steering link 23 and also points in a direction toward the steering lever 21.
  • the abutment nose 29 engages an additional abutment pin 26 which is secured in position to the mattress element 12, so that the kinematic linkage 20 is held in a stable position and keeps the mattress element 12 in its position illustrated in FIG. 9.
  • a tension spring 27 which is secured, on the one hand, to the common pivot 24 and, on the other hand, to a connecting region of the steering lever 21 with the mattress element 12.
  • An important feature of the present invention is that, as can be easily ascertained from FIGS. 7 to 9 of the drawing, the distance between the connection region of the steering link 23 and the connection region of the steering lever 21 to the mattress element 12 is smaller than the distance between the connection region of the steering link 22 and the connection region of the steering lever 21 to the bed frame 13.
